Byagaragaye ko ibiciro byibicuruzwa bya shimi kumasoko bikomeje kugabanuka, biganisha ku gihe cyo kugaburira agaciro mumirongo myinshi yinganda. Ibiciro byamavuta maremare byiyongereye igitutu cyikibazo cyurubuga rw'inganda, kandi ubukungu bw'ibicuruzwa by'ibicuruzwa byinshi bya shimi birakennye. Ariko, igiciro cyisoko cya vinyl acetate nacyo cyagabanutseho gusubizwa, ariko inyungu z'umusaruro zakomeje kuba hejuru kandi ubukungu bwumusaruro ni bwiza. Noneho, kuki Uwiteka ashoboravinyl acetateIsoko rikomeza iterambere ryiterambere?

Nko mu mpera za Kamena 2023, igiciro cy'isoko cya vinyl acetate ni 6400 yuan / toni. Ukurikije urugero rwibiciro byibikoresho fatizo kuburyo bwa Rowyne hamwe nuburyo bwa Calcium Carbide, uburyo bwibanze kuri 14%, mugihe inyungu za Calcium Carbide uburyo butaje. Nubwo igabanuka rihoraho ryigiciro cya vinyl acetate umwaka, inyungu ya Ethyle ishingiye kuri Vinyl Acetate akomeje kuba hejuru, agera kuri 47% mugihe cyimibare myinshi ya margin mubicuruzwa byinshi. Ibinyuranye, uburyo bwa calcium carbide ya vinyl acetate bwabaye mugihombo kinini mumyaka ibiri ishize.

Mugusesengura impinduka mu nyungu za Ethylene ishingiye kuri Vinyl Acetate na Calcium ishingiye ku majwi ya vinyl acetate yahoraga yunguka Inyungu za Margin Urwego rwa 15%. Ibi byerekana ko Etyley ashingiye kuri Vinyl Acetate yunguka inyungu mumyaka ibiri ishize, hamwe nubutera imbere muri rusange hamwe nimpande zihamye. Mu myaka ibiri ishize, usibye inyungu zikomeye kuva ku ya 20 Werurwe22 kugeza 2022, uburyo bwa calcium carbide ya vinyl acetate bwabaye mu bindi bihe byose. Kugeza ku ya 2023 Kamena3, urwego rwinyungu rwa Calcium Carbide ya Vinyl Acetate yari afite igihombo cya 20%, hamwe na maringi ya Calcium ya Calcium Carbide Mu myaka ibiri ishize yari 0.2%. Duhereye kuri ibi, birashobora kugaragara ko gutera imbere kwa Calcium carbide kuri vinyl acetate ni umukene, kandi ibintu rusange byerekana igihombo.

Binyuze mu bindi bisesenguzi, impamvu nyamukuru zituma inyungu nyinshi zishingiye ku misaruro ya Ethylel ishingiye ku musaruro wa Vinyl Acetate ni utya: Ubwa mbere, igipimo cyibikoresho bifatika mumikorere itandukanye yumusaruro biratandukanye. Muri rosylene ya Ethylen ya vinyl acetate, ikoresha igice cya Ethylene ni 0.35, hamwe nigice cyo gukoresha acide yinda ni 0.72. Dukurikije impuzandengo y'ibiciro muri Kamena 2023, inkuru za Ethylene zigera kuri 37% yikiguzi cya Ethylene gishingiye kuri vinyl acetate, mugihe konti zidasanzwe za acetic kuri 45%. Kubwibyo, kubwingaruka z'igiciro, ihindagurika ry'ibiciro rya acide y'ikirere rifite ingaruka zikomeye ku guhindura idini ry'ibiciro bya vinyl ashingiye kuri vinyl acetate, akurikirwa na Ethyne. Kubijyanye n'ingaruka ku giciro cya Calcium Carbide Dinyl Acetate, igiciro cya Calcium Carbide ya Calcium ACETATE uburyo bwa charcium kuri calcium . Kubwibyo, muri Calcium Carbide ya Vinyl Acetate, guhindura igiciro bya karbide calcium bigira ingaruka zikomeye kubiciro. Ibi biratandukanye cyane ningaruka zamakuru ya Ethylene.

Icya kabiri, kugabanuka mubikoresho bibisi Ethyne na acide yita acetike byari bifite akamaro, bituma habaho kugabanuka kwinshi. Mu mwaka ushize, igiciro cya CFR y'Amajyaruguru ya Aziya Ethylene cyagabanutseho 33%, kandi igiciro cya acide kitarangwa cyaciwe na 32%. Ariko, ikiguzi cya vinyl acetate cyakozwe nuburyo bwa Calcium carbide ahanini bibuza cyane nigiciro cya calcium carbide. Mu mwaka ushize, igiciro cya Carcium Carbide yagabanutseho 25%. Kubwibyo, ukurikije uko ibintu bibiri bitandukanye binyuranye, ibiciro byibikoresho bya vinyl acetate byagabanutse neza, kandi kugabanya ibiciro birarenze ibyo muburyo bwa Calcium Carbide.

Nubwo igiciro cya vinyl acetate cyagabanutse, kugabanuka kwayo ntabwo ari ngombwa nkindi miti. Ukurikije kubara, mumwaka ushize, igiciro cya vinyl acetate cyagabanutseho 59%, bishobora gusa nkingirakamaro, ariko ibindi bikoresho byahuye nabyo. Imiterere idakomeye yisoko ryimiti yubushinwa iragoye guhinduka muburyo bwihuse. Biteganijwe ko ejo hazaza, hari amahirwe menshi yo gukora isoko ryanyuma, bikaba ibicuruzwa nka polyvinyl na eva, bizakomeza kwiyongera no guhagarika inyungu za vinyl acetate.

Hariho ubusumbane bukomeye mumitsi yinganda zubu, kandi ibicuruzwa byinshi biri mubiciro byinshi ariko bikaba umuguzi uhagije, bikaviramo ubukungu buke. Ariko, nubwo bahuye nibibazo, isoko rya Vinyl Acetate ryakomeje inyungu nyinshi, cyane cyane kubera ibiciro bitandukanye byamafaranga yibiciro byibiciro byayo no kugabanya ibiciro biterwa no kugabanuka kw'ibikoresho bibisi. Ariko, imiterere idakomeye yisoko rya shimi y'Ubushinwa biragoye guhinduka. Biteganijwe ko ejo hazaza, hari amahirwe menshi yo gukora isoko ryanyuma, bikaba ibicuruzwa nka polyvinyl na eva, bizakomeza kwiyongera no guhagarika inyungu za vinyl acetate.
